For some reason I can't understand, I fell again into one of those infinite loops of MessageNotUnderstood exceptions that usually take the system down. But this time I was able to interrupt it by pressing Alt+., and then I closed all the debuggers and opened windows. Trustworthy (aka stupid) as I can be, I saved the image, but then every time I tried to debug some test case, only one frame on the debugger was visible, and any attempt to evaluate something within it lead me to another infinite MNU wormhole. Now when I start the image I get a ProcessAlreadyTerminating walkback, without much to do (see http://i.imgur.com/fxo17pN.png). But I'm still unable to debug any method using the Glamourous Debugger. I can if I disable it. I don't know whether the Glamourous debugger and the process thing are related, but I'm sharing this just in case somebody has an idea on how to fix the walkback and the GTD.
